Description

Technical Field

[0001] The utility model belongs to the technical field of automobile wheel rims, and particularly relates to a wheel rim with a surface coated with a hydrophobic material. Background Art

[0002] The wheel hub, commonly known as the rim, is a component that mounts and supports the tire around the wheel. The wheel hub supports the weight of the vehicle and the weight of the passengers during the movement of the car, and requires high structural stability. In addition, the vehicle usually drives over flooded roads during driving, and encounters rain and snow during daily driving. In this case, coating the wheel hub with a certain hydrophobic layer can help reduce rim corrosion caused by corrosive water vapor.

[0003] In the existing technology, the wheel hub metal is generally protected by chrome plating. In this method, after the surface of the chrome plating layer is wetted by liquid, the hydrophobicity of the chrome plating layer will be greatly reduced, and sewage sludge and the like are easily attached to the surface. In addition, current tire pressure monitoring is generally divided into active and passive types. However, both tire pressure monitoring methods require the laying of lines. When modifying vehicles that do not have tire pressure monitoring function when leaving the factory, the modification cost is high and there are certain circuit risks. Utility Model Content

[0004] In response to the above problems, the purpose of the present utility model is to provide a wheel rim with a surface coated with a hydrophobic material to solve the problem that the existing method of protecting the wheel hub by chrome plating has poor hydrophobic performance; and the problem that the cost of installing a tire pressure monitoring function on the wheel hub is high and has certain circuit hidden dangers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wheel rim with a surface coated with a hydrophobic material, comprising a wheel hub, the surface of the wheel hub being sprayed with a fluorocarbon coating, the wheel hub being provided with an internal threaded hole for threaded connection to a quick-install tire pressure monitoring assembly, the quick-install tire pressure monitoring assembly comprising an externally threaded tube, one end of the externally threaded tube being connected to a cylinder body, one end of the cylinder body being connected to a nut, the nut being threadedly connected to the externally threaded tube, a turning handle and a piston being respectively installed at both ends of the externally threaded tube, the piston being slidably installed on the inner side of the cylinder body, a pressure plate being provided on the outer side of the externally threaded tube, an indicator rod being slidably inserted in the externally threaded tube, a spring being sleeved on the indicator rod between the pressure plate and the piston, and a groove body being provided on the indicator rod for adapting to the installation of the indicator part.

[0006] The beneficial effects of the present invention are as follows: the fluorocarbon coating applied on the surface of the wheel hub has self-cleaning properties and excellent weather resistance, can maintain hydrophobic properties for a long time, and avoid liquid adhesion; the quick-install tire pressure monitoring component is easy to install, and when the tire pressure drops, the indicator can be moved inward and retracted through the mechanical structure, and by observing the indicator light of the indicator, it is possible to intuitively and quickly judge whether the tire pressure is lower than the safe value.

[0007] In order to make the fluorocarbon coating play an effective hydrophobic role;

[0008] As a further improvement of the above technical solution: the average spraying thickness of the fluorocarbon coating is 70-90 μm.

[0009] The beneficial effect of this improvement is that the fluorocarbon coating has good hydrophobic properties and can effectively prevent rainwater and road sewage from adhering to the surface of the wheel hub.

[0010] In order to effectively ensure the sealing of the piston to the gas in the tire;

[0011] As a further improvement of the above technical solution: a dynamic sealing ring is provided on the outer side of the piston, the dynamic sealing ring and the cylinder body are interference fit, and the connection between the external threaded tube and the wheel hub is coated with sealant.

[0012] The beneficial effect of this improvement is that the provision of the dynamic sealing ring effectively ensures the airtightness of the tire and prevents the gas inside the tire from leaking to the outside through the quick-install tire pressure monitoring assembly.

[0013] In order for the spring to provide stable elastic support for the piston;

[0014] As a further improvement of the above technical solution: one end of the spring is sleeved on the outside of the externally threaded tube.

[0015] The beneficial effect of this improvement is that the externally threaded tube plays the role of limiting the connection spring, so that the spring maintains a stable position when subjected to pressure from the piston and the pressure plate.

[0016] In order to make the external threaded tube slide and rotate smoothly on the outside of the indicator rod;

[0017] As a further improvement of the above technical solution: the indicator rod is a round rod structure, and the indicator rod and the external threaded tube are clearance-fitted.

[0018] The beneficial effect of this improvement is that the indicator rod can move linearly and rotate smoothly relative to the externally threaded tube.

[0019] In order to make the indicator visible and clear both during the day and at night;

[0020] As a further improvement of the above technical solution: the indicator is a tritium gas tube structure.

[0021] The beneficial effect of this improvement is that the indicator can emit light for a long time, so that it can be observed clearly and intuitively both during the day and at night.

[0022] In order to make the indicator visible to people at different angles;

[0023] As a further improvement of the above technical solution: there are multiple indicating members, and they are arranged at equal intervals around the axis of the indicating member.

[0024] The beneficial effect of this improvement is that multiple indicators can be observed intuitively and conveniently by personnel.

[0025] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figure 1—5 shows: a wheel rim with a surface coated with a hydrophobic material, comprising a wheel hub 1, the surface of the wheel hub 1 being sprayed with a fluorocarbon coating 2, the wheel hub 1 being provided with an internal threaded hole for threaded connection to a quick-install tire pressure monitoring assembly 3, the quick-install tire pressure monitoring assembly 3 comprising an externally threaded tube 31, one end of the externally threaded tube 31 being connected to a cylinder 32, one end of the cylinder 32 being connected to a nut 33, the nut 33 being threadedly connected to an externally threaded tube 34, a handle 39 and a piston 37 being respectively installed at both ends of the externally threaded tube 34, the piston 37 being slidably installed on the inner side of the cylinder 32, the externally threaded tube 3 4 is provided with a pressure plate 36 on the outside, and an indicator rod 40 is slidably inserted in the external threaded tube 34. A spring 35 is set on the indicator rod 40 between the pressure plate 36 and the piston 37. A groove body for mounting an indicator member 41 is opened on the indicator rod 40. The fluorocarbon coating 2 coated on the surface of the wheel hub 1 has self-cleaning properties and excellent weather resistance, and can maintain hydrophobic properties for a long time to avoid liquid adhesion; the quick-install tire pressure monitoring assembly 3 is easy to install. When the tire pressure drops, the indicator member 41 can be moved inward and retracted through the mechanical structure. By observing the indicator light of the indicator member 41, it is intuitive and quick to judge whether the tire pressure is lower than the safe level. value, the average spraying thickness of the fluorocarbon coating 2 is 70-90μm, the fluorocarbon coating 2 has good hydrophobicity, which can effectively prevent rainwater and road sewage from adhering to the surface of the wheel hub 1, and a dynamic sealing ring 38 is provided on the outside of the piston 37. The dynamic sealing ring 38 and the cylinder body 32 are interference fit. The connection between the external threaded tube 31 and the wheel hub 1 is sealed with sealant. The setting of the dynamic sealing ring 38 effectively ensures the airtightness of the tire and prevents the gas in the tire from leaking to the outside through the quick-install tire pressure monitoring component 3. One end of the spring 35 is sleeved on the outside of the external threaded tube 34, and the external threaded tube 34 is used to The limit connecting spring 35 is used to keep the spring 35 in a stable position when it is under pressure from the piston 37 and the pressure plate 36. The indicator rod 40 is a round rod structure, and the indicator rod 40 and the external threaded tube 34 are clearance-fitted. The indicator rod 40 can move and rotate smoothly in a straight line relative to the external threaded tube 34. The indicator part 41 is a tritium gas tube structure, and the indicator part 41 can self-luminesce for a long time, so that it can be observed intuitively and clearly both during the day and at night. There are multiple indicators 41, and they are equidistantly spaced around the axis of the indicator part 41. Multiple indicators 41 can be easily and intuitively observed by personnel.

[0035] The working principle of this technical solution is as follows: the hydrophobicity of the fluorocarbon coating 2 can effectively prevent rainwater or ground sewage from adhering to the surface of the wheel hub 1, thereby reducing the difficulty of cleaning the wheel hub 1 and preventing muddy water from adhering to the surface of the wheel hub 1 and being thrown out to wear the surface of the wheel hub 1 during the high-speed rotation of the wheel hub 1; when installing the quick-install tire pressure monitoring assembly 3, an internal threaded hole interface for installing the quick-install tire pressure monitoring assembly 3 is drilled on the wheel hub 1 to quickly install the quick-install tire pressure monitoring assembly 3 on the wheel hub 1 for use; after the quick-install tire pressure monitoring assembly 3 is installed on the wheel hub 1, the tire is installed on the wheel hub 1, and a sealing ring is driven into the tire. Appropriate air pressure is adjusted, and then dynamic balance adjustment is made on the wheel hub 1; the gas in the tire pushes the piston 37 upward, which causes the spring 35 to produce elastic deformation and pushes the indicator rod 40 to move toward the upper side of the turning handle 39; the turning handle 39 is rotated, so that the indicator rod 40 pushes the piston 37 downward until the indicator member 41 is just outside the turning handle 39; when the tire pressure decreases, the spring 35 releases part of its elastic potential energy, pushing the piston 37 toward the direction of the external threaded tube 31. When the external threaded tube 31 moves, it drives the indicator rod 40 downward, and then drives the indicator member 41 to move to the inside of the external threaded tube 34, so as to intuitively judge whether the tire pressure is too low.
